In the second stage of the simulation the SPICE circuit simulator is executed on the circuit file that was exported in the first stage. A transient analysis is performed according
to the settings of the VCL oscilloscope. The results of the SPICE simulation are written to a new file in the default directory.
Finally, in the third stage of the simulation, the SPICE output file is read into the VCL and the data from the transient simulation is extracted then displayed in the oscilloscope window.
